Models
A model is a special kind of description of how something happens
in the world. A model contains a description of the things in a system, descriptors
of those things and the relationships among them.
Reusing Models
Any model you make is stored in your model library. You can reuse that model either as a building block, or you can cut and paste that model into new models. If you need to change something in the model to fit a new situation, you can do so.
